IMPROVEMENT IN Y sAwlNe-M'Acl-MNE TABLES.

I T ho Schedule referred to in thele Letters Patent and making part of the lame.

I, J ONA'IHAN OREAGER, of" Cincinnati, Hamilton county, Ohio, have invented-a new and useful SawingllLIachineTable for Thin Stu, of which lthe following General Description with Reference to the Drawing.

Figures' 1 and 2j are, respectively, a perspectivel and a top View of .a sawing-,machine embodying my improvements.

Figure 3 is a front elevationof the saw and its im- A represents abench or table, under`- which. is journaled' the arbor .B of a customary veneer-saw, C-that Ais to say,a circular saw with very. thin cutting-edge, and yhaving a thick central 'portion 'or hub.

Parallel with the arbor,' and 'protruding slightly above the top of the bench, is av series of rollers. D, whose oice is to support thestu' and to facilitate its advance in the act of cutting. .Y

E is a bearing-off plate, which, rising vertically from the bench, nearly touches the saw-blade on. its rear 'side a little back of its cutting-edge, with which it corresponds in contour, and .from which it extends obliquely rearward in the manner represented.

The plate E is attached to the bench by bolts F,

which traverse slotted lugs G'that project from said plate.

These bolts occupy slots c in the bench parallel with the saw. This double system of slots renders the bearing-oli' plate adjustable to any desired position or anule.

A Fuller, H, jonrnaled vertically in the said plate, and protruding slightly beyond the rear or workingface thereof, serves to ease the partially-severed board past the saw While properly opening the kerf for its action.

I is a gauge-strip, attached, by bolts J, to a foot# piece, K, which foot-piece is attached, by bolts L, to the bench. 4

The said bolts occupying slots tand k in the' strip and footpiece, respectively, enable any desired adjustment of the gaugeepiece, either parallel or vertical to the saws plane.

Journaled vertically in that portion of the gaugestrip nearest the saw, and adjustable in said strip, are

two rollers, M N, which are set in such relatively: oblique or raking lposition as to bring the lower edge o'f the roller immediately in rear of the saws periphery at that pait. I

.This vraking seris'' rollers M N serves to guide the stuff u'p to and past the saw, and to hold it uuiformly thereto at every part.

While "describing the' preferred form of my invention, I reserve the right to vary the same so long as I attain therequired results by means substantially equivalent; for example, twoor more rollers may `be used in the'bearing-oii' plate incombination with one or more gauge-rollers.

Where a series o f gauge-rollers is employed, their `upper ends may, if preferred,"'rise to a common level, as it is only' necessary for their lower -ends to follow the curve of the saw.

The gauge-strip and foot may be in one piece, longitudinal adjustment being provided for by slots in the bench.

The piece E may bevcomposed of wcod'or of metal, or both combined.

For saws ot' larger diameter the number of my raking gauge-rollers may be increased.

A Gla/im. v f

The described arrangement of veneer-saw C, supporting-rollers D, obliquely-ascending series of gaugerollers lM N,"and the bearing-oli' roller H, for the purpose set forth.

In testimony of which invention I hereunto set my hand.
